中文摘要: |
【目的】为研究鸡鸡冠性状和72周龄产蛋性状共9个指标间相关关系,分析两组性状组间关系,【方法】以东乡绿壳蛋鸡和单冠白莱航鸡为亲本构建的资源群体F2代为素材,测定鸡冠性状和72周龄部分产蛋性状。【结果】结果表明,9个变量中共有24对相关性达到极显著水平(P<0.01), 其中冠重和冠面积间相关系数最大,达到0.846。典型相关分析中,鸡冠性状和72周龄产蛋性状第1典型相关系数为0.203,达到极显著水平(P<0.01),【结论】两组性状之间的相关主要是由冠高、冠面积、72周龄产蛋数、72周龄蛋重和72周龄蛋壳强度间的密切相关引起的。 |

【Objective】In order to study the correlation in 9 indexes between comb traits and egg productive traits at 72-week-old chickens, analysis the relationship between the two groups. 【Method】The comb and egg productive traits at 72-week-old chickens were determined by using the resource population F2 which was established by Dongxiang Green-shell laying hens and single-comb White Leghorn chicken as materials. 【Result】The results showed that 24 pairs of correlations among 9 variables reached extremely significant (P < 0.01), the correlation coefficient between comb weight and comb size was the largest, which was 0.846. the first canonical correlation coefficient between comb traits and productive traits was 0.203, which was extremely significant (P < 0.01). 【Conclusion】The correlation between the two traits was mainly caused by comb height, comb size, egg number, egg weight and eggshell strength at 72-week-old, respectively. |
